Issue:
After changing the email address associated with my ChatGPT/OpenAI account, the ChatGPT macOS app repeatedly shows the login page.

Description:
I successfully changed my account email address. Since then, whenever I open or use the ChatGPT macOS app, I am redirected to the login page and asked to sign in again. Even after successfully logging in, the login page keeps appearing.

Expected behavior:
After signing in once with my updated email address, the macOS app should keep me logged in normally.

Actual behavior:
The app repeatedly returns to the login screen, making it difficult to use the app normally.

Platform: ChatGPT for macOS

Steps to reproduce:

1. Change the email address associated with the ChatGPT account.
2. Open the ChatGPT macOS app.
3. Sign in with the updated account information.
4. Continue using or reopen the app.
5. The login page appears again.
